HELMET.

To all whom t may concern ABe'it known that I, ROBERT MALCOM, a

citizen of the United States, residing at Chiicago, Cook county, Statel of Illinois, have invented certain new and useful Improvements in Helmets, of which'the following, taken in connection with the drawings, is a description.

My invention has for its object the production of a helmet, designed more particularly for use in welding, or similar operations where it is necessary to protect the eyes of the wearer from extremeheat and brilliant light, which can be readily placed in position or removed, dand one which will protect both the eyes and head of the wearer.

A` further object of my inventionl is to.

provide a helmet of the class described, formed of non-inflammable, non-heat -conducting material, which, when in use, rests upon the shoulders of the wearer, and which protects the head from heat and the eyes from brilliant light. A

Another object of my invention is the production of a head protector or helmet of the class described, adapted to beV placed over the head of the wearer, the lower end of which conforms to the outline of his shoulders, and thel upper end being open,

' which in connection with slots nearthe lower end thereof, provides sufficient ventilation.

A further object of my invention is to provide a helmet designed more particularly for use in. welding or similar operations, having two inde endent setsof glasses or lenses. @neef w iicli is relatively darle in color, and which may be moved out of alinement with the eyes and returned to the original position when desired.

therobjects will appear hereinafter.

In the accompanying drawings I .havey Villustrated what I now consider the preferi'ed form ofmy invention, although` I wish to be understood as contemplating such modifications and variations as come within the scopel of the appended claims, and in front elevation of my de- Specification of Letters Patent. Patented June 10, 1919. aiipiication md september 5, 191s. serial No. 252,752.

i formed of suitabley non-inflammable inaterial, such as fiber. It may consist of two pieces, a front portion, 6, and a rear portion, 7, as illustrated, or it maybe formed of a single piece of material. two piece construction is used, the parts may be secured to each otherby rivets 8, or in any other suitable manner. The back portion, 7 is preferably bent vso that the hel-y met is substantially semi-elliptical in cross section, as shown' inI Fig. 3. v

The lower edge, ,9, is shaped to'conform to the body of the wearer, the sides resting lupon his shoulders, and the weight of the 10 `are provided preferablynear the lower edge of the helmet, to facilitate ventilation.

When vthe On the front of the helmet, at points` be substituted for said eye cups with equally good results.

The glasses or lenses, 12, are removably secured in said eye cups, as'shown in Fig. 3.

lThe lens holding frame, 13, is positioned over the eye cups, 11, and is movably mounted on the frame, 14, at 15, as shown in Fig. l. The frame, 14, is secured to the helmet by the screws, 16, or by any other suitable means. The lenses, 17, are mounted in said frame, as shown in Fig. 3, andare of relatively dark color. Said lenses, 17, of which there `are preferably a plurality, as shown in Fig. 3, .are of suiiicient densityy to protect the wearers eyes from'the brillianty light incident to Oxy-acetylene welding and the like.

` The coil springs, 18, lare .secured to the helmet at 19, and to the frame, 13, at Q0. These springs are so arranged that when the frame, 13, is in loweredl position, as in Fig. 1, it is firmly held in place by the tension of said springs, and when inv raised position, as indicated by the dotted lines in"Fig. 1, i't is firmly held in place by the tension of the springs.

When the helmet is in position, the vback of the wearers-head contacts with the rear of the helmet, and the helmetis tilted slightly forward, so that thelower edge of the front side thereof contacts with thewearers chest. The top of the helmet is open, thereby providing ample ventilation.

y, During the welding operation7 the frame,

70 helmet being supported thereby. The slots,

13, is in lowered position, so that the eyes of the operator will be protected from t-he otherwise blinding light. When, however, the llame is temporarily shut off, the lenses, 17, are of such density as to obscure the vision of the wearer. i The frame,'13, may then be 'raised to the position indicated in dotted lines in Fig. 2, thereby obviating the necessity of removing the helmet. Vhen the frame is raised, the lenses, 12, protect ythe eyes from loose particles which may be in the air.

I claim:

1. A helmet or head protector, comprising a body portion adapted to fit over the head of the wearer and to rest upon the shoulders, both ends of said helmet being open, said helmet being provided with openings in the front thereof, and glasses or lenses mounted in said openings. p

2. A helmet 'comprising a shell adapted to lit over the head of the wearer and to rest upon the shoulders, said helmet being substantially semi-elliptical in cross section, and formed of non-heat conduct-ing material, said helmet having the upper end thereof open, and having a plurality of openings arranged therein to permit continuous passage of air therethrough, and said helmet having openings in the frontthereof, and glasses or lenses mounted in said openings.

3. A helmet comprising a body portion vadapted to tit over the head of the wearer,

and having its lower edges shaped to conform to 'the outline of the shoulders, said helmet having 'openings therein. so positioned as to permit the passage of air therethrough, and two independent sets of glasses or lenses mounted on said helmet in alinement, with each other.

4. A helmet, comprising an elongated shell, substantially semi-elliptical in cross section, and having its lower edges shaped to conform to the outline of the shoulders of the wearer, and two independent sets of glasses or lenses, one being mounted in said helmet, and the other movably mounted thereon, said helmet having openings therein so positioned as to permit the passage of air therethrough.

5. A device of the class described, oomprising a shell adapted to llit over the head of the wearer and to rest upon the shoulders,-

two independent sets of glasses or lenses mounted thereon, one of said sets of lenses being relatively dark in color, and means for moving said last mentioned set of`lenses out of alinement with said other set of lenses. Y

6. A helmet comprising a shell ada-pted to fit over the head of the wearer, and having its lower edges shaped to conform to the outline of the shoulders, two independent sets of lenses, one beingpmounted in said helmet, andthe other being mounted in a frame, said frame being movably mounted on .said helmet, and adapted to be raised out of alinement with said first mentioned lenses, means for holding said frame in raised position, and means for holding said frame in lowered position, substantially as described.

In testimony whereof I have signed this specification.

ROBERT MALCOM.
